Abstract: Already in the fifties conventional power plants with high parameters of the live steam were built to improve the total efficiency. The power plant with the highest steam conditions in the Federal Republic of Germany has 300 bar pressure and 600 °C temperature. Because of high material costs and other problems power plants with such high conditions were not continued to be built. Standard conditions of today's power plants are in the order of 180 - 250 bar pressure and 535 °C temperature. The presented work investigates the potential of the high temperature reactor for highest steam conditions. As the high temperature reactor is partly built up in another way than a conventional power plant, the results regarding the high steam parameters are not transferable. Possibilites for the technical realization of determined HTR-specific components are introduced and discussed. Then different HTR-power plants with steam conditions up to 350 bar pressure and 650 °C temperature are projected. The HTR is constructed that way, that conditions of 350 bar/ 650 °C can be realized. Economical considerations show that an HTR with higher steam parameters brings financial profits. Further efficiency increase, which is possible by the high steam conditions, is shortly presented. Very high efficiences can be reached, if a helium gas turbine is coupled with an over-critical HTR-steam power process. The work ends with a technical and economical comparison of corresponding conventional power plants.
